Device parameters container available only for iiziRun. It is used to store
device parameters on the device that can be sensitive, thus secured by encryption.

Sensitive parameters are encrypted with a key kept on the server side. The
encrypted data is padded and sent to the client and no key is used on the client side.
Only the fingerprint of the server key used is included in the encrypted data. This
means that the sensitive parameter is virtually undecipherable on the client side.
